This episode, I speak to University of York’s Heather Marsden about the controversial Critical Period hypothesis. This theory suggests that there is a limited age at which we can learn a second language, after which it grows increasingly difficult. Anecdotally, we assume this to be true – kids are sponges for language while older people struggle – but what does the research say about this?

This episode is simply a bite-sized introduction to a much larger topic, so I encourage you to search around for other perspectives on this subject.
